Problems solved by technology

[0008] The disadvantages of the prior art: 1. The production cost of the substrate is high, and some components are difficult to obtain; 2. The formula of the soilless substrate ensures the ventilation and water permeability of the substrate, but at the same time, the water and fertilizer retention capacity is poor, which is not conducive to the growth of seedlings
3. The labor cost is increased through the topdressing in the later stage of transplanting

Embodiment Construction

[0012] The substrate of the present invention is mainly composed of sawdust, peat soil and red loam, the volume ratio is 2:1:1, and the pH value of the substrate should be controlled between 6.2 and 6.8.

[0013] Apply 1 / 25 to 1 / 5 of the matrix volume of organic fertilizer and 1 / 150 to 1 / 50 of the matrix volume of calcium magnesium phosphorus in the matrix.

[0014] The addition of fertilizer is only to reduce the management of topdressing in the later stage and reduce labor costs. The addition of fertilizer can be used as a subsidiary right. The volume of organic fertilizer is 1 / 5-1 / 25, and the volume of calcium, magnesium and phosphorus is 1 / 50-1 / 150.

[0015] PH value Adjust the pH value of the matrix by adding quicklime.

[0016] A large number of studies and practices believe that organic fertilizers have comprehensive nutrients and long-lasting fertilizer effects. Organic fertilizers not only contain the macroelements and trace elements necessary for plants, but also ri...

Abstract

An optimized substrate for tissue culture, transplantation and hardening-off of gerbera jamesonii relates to a method for tissue culture of flowers, which is characterized in that the substrate mainlyconsists of saw dust, moor soil and laterite according to the volume proportion of 2:1:1, and the pH value of the substrate is controlled between 6.2 and 6.8. The method has the following advantagesthat: the adding of the saw dust saves cost, and simultaneously improves the ventilation capability and water permeability of the substrate; as a conventional component of a soilless culture medium, the moor soil guarantees various physico-chemical structures of the substrate; and the adding of the laterite not only can adjust the pH value of the substrate, but also can enhance the water-holding and fertilizer-conserving capacity of the substrate.

Description

Technical field: [0001] The invention relates to a method for growing flower tissue cultured seedlings, in particular to a substrate for transplanting gerbera chrysanthemum tissue cultured seedlings. Background technique: [0002] Gerbera, scientific name Gerbera jamesonii Bolus, is a perennial herbaceous plant of the genus Gerbera in the Compositae family. It is one of the five largest cut flowers in the world. Therefore, it is favored by consumers. [0003] Since most gerbera are self-fertile and sterile, the offspring of hybrids will split and mutate. Conventional propagation adopts the division method, but the reproductive coefficient is low, which cannot meet the needs of large-scale production. In order to quickly obtain a large number of high-quality, virus-free seedlings, it is an effective way to use tissue culture technology to carry out the production of gerbera seedlings, and the transplanting and domestication of test-tube seedlings is a key step in the rapid p...
